BUILDING.

Application filed June 15, 1923. Serialit'o. 645,598.

To all whom z'tmay concern:

Be it known that I, SAMUEL W. SIDER, citizen of the United States, residing at Logansport, in the county of Cass and tate of Indiana, have invented certain new and useful Improvements in Buildings, of which the following is a specification.

This invention relates to buildings and.

specifically to silos, bins, water tanks and the like.

The primary object of the invention is to provide such a building constructed of improved forms of terra cotta blocks or staves.

A further object of the invention is to furnish blocks or staves of improved construction, which are provided with means for maintaining the ribs of superposed staves in vertical alignment.

Another object of the invention is to furnish blocks having ribs provided with spaced grooves ada ted to receive the hoops which encircle the uildin A still further ob ect is to provide the rib of each block with a plane surface so as to permit the hoop to bear on the heel of the rib and to allow the hoop to ride on the heel in turning a small circle.

A further object is to furnish a bin or silo constructed of these improved blocks and provided with a simply constructed continuous doorway reaching from the top of the building to the bottom of the same or to a point adjacent to the bottom of the same.

This continuous doorway is obstructed at spaced levels by cast iron door spreader members and the blocks forming the door jambs are provided with special recesses to receive the cast iron Spreaders.

A still further object is to provide a chute for the bin or silo, of special construction.

With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a top plan view of a portion of a silo provided with a discharge chute, and constructed in accordance with the invention.

Fig. 2 is a perspective view of one of the specially formed blocks made in accordance with the invention.

F1g. 3 is a front view of said block partly in section.

Fig. 4 is a front view of a portion of a s lo to illustrate the manner of constructing silos in accordance with the invention.

For the. purpose of disclosure, it is to be noted that the block forming part of the invention is an improvement over the block shown in the patent to W. A. Hillman No. 1,086,295, dated February 3rd, 1914.

In the drawing, 8 designates one of the main blocks of the type which may be employed to construct silos, bins, water tanks, etc. This block is of general rectangular shape and one of its side edges is convexed as shown at 9 from one end of the block to the other. The other side edge portion of the block has an outwardly pro ecting rib 10, the inner surface 11 of which is concaved to receive either the convexed edge of an adjacent block in the main silo structure or to bear upon the outer surface 12 of the rib in some cases where a chute is formed on a silo, (see 13 in Fig. 1). The longitudinal central portion of the outer surface 12 of the rib 1s preferably in a plane 14, and the rib has spaced horizontal grooves 15 formed in this plane surface and extending to the heel 16 of the rib, for a purpose hereinafter described.

The upper end of each rib is provided withan integral dome or convex button 17, which is adapted to enter a dome-shaped recess 18 provided in the opposite end of a superposed block. This button and recess construction holds the ribs of superposed blocks in line in constructing a silo, tank or the like, and the dome shape oi? the button and recess prevents the button from shearing 01f. These elements also form a lock for the continuous rib formed by the superposed ribs of the blocks, and as the steel hoo s or bands 19 do not catch all joints, it is o vious that when the pressure comes in filling the silo or the like, the buttons will have to be crushed ed to weaken the construction. In other words at points in the silo where the hoops do not engage the ends of the ribs, the buttons will function to lock the ribs in alignment. The inherent strength of concrete against crushing is many times greater than its tensile strength,

so by having a button on one end of the button and recess also ermits building of a construction at 001181 erably less expense than the known constructions, and also allows the breaking of joints in erecting. For example in constructing a silo or the like, staves 12 inches by 30 inches with a rib 4% inches thick cast on one edge and the stave of 21 inches thickness are provided. Other staves 24 inches long are also made. In setting a circular construction, a start is made with staves 30 inches long for the first horizontal course, and these staves are spaced apart by staves 24 inches'in length, so that the 24 inch staves alternate with the 30 inch staves for the first complete circle. Then after placing the hoops on this lower course and leaving the to hoop loose another comlete circle of 30 Inch staves only is made.

hen the top hoop is. ti htened, and subsequent courses of' 30 inc staves are superposed until the required height is obtained. Then to level up the structure at the top caused by using 24 inch staves in the first circle, use is made of 6 inch staves in the top circle. It will be understood that during this erection, the buttons 17 and recess 18 will facilitate the positioning of the blocks. The grooves 15 in the ribs which receive the hoops 19 permit the placing of the hoops at various points along the staves. In the building of large bins such as coal pockets, grain bins and so forth, it is necessary to hoop the structure strong enough to withstand the internal pressure. Diiferent sized bins require hoops spaced differently, and this requires the grooves 15. Any size bin can be erected and allow for any size capacity by the arrangement of the grooves in the present invention.

In Fig. 1 at 20, the heel of the rib is shown riding on the hoop 21 of the discharge chute 22. Prior to the present invention it was found necessary in almost every case, where the chute was constructed of interlocking blocks, to chip out part of the rib in order to permit the hoop to bear evenly on the ribs of the blocks of the discharge chute. But by providing the plane surface 14 on the ribs in the present construction, the hoops may ride evenly on the heels of the ribs and the hoops will bear on the ribs for quite a distance in contradistinction to the point contact present heretofore. It has been found in actual practice that a small circle for the discharge chute may be effected easily without loss of time by the present construction.

Where it is desired to place a discharge chute alongside the silo or the like, it is also desirable to have a door opening from the silo into the chute throughout substantially the entire length of the chute, and to accomplish this pur ose, the blocks 23 at the opposite sides 0 the doorwa each provided with upper and ower recesses25 and 26. These recesses receive and lock in' place, the ends 27 of doors reader bars 28. One of these spreader are is preferably placed at the joint between each Fig. 4, and the ends 27 of the spreader bar are rabbeted or recessed as shown at 29 in Fig. 1' to receive removable doors 30. This continuous doorway is large enough to permit eas access from the interior of the silo into t e chute and vice versa, and it is readily constructed and therefore effects a great saving of time and money for the purpose. In throwing down the feed through the chute, the opening is always at hand and it is not necessary for a man feeding to lift the feed into the chute, as would benecessary if part of the doorway were closed. Thls continuous doorway also eliminates the making ofv heav square doorframes, which re uire none more time to make than does t e stave or blocks of the 24, are

superposed course of blocks, as shown in present invention, and much more time to set than the present staves or blocks.

ard silo staves or blocks, such as are used in the silo proper; A great many users desire a chute on their silo and most of them have gone to the expense of having this chute built of wood or sheet steel, which considering the cost of labor and material for a special job, amounts to a great deal more than the cost of a chute built of staves such as described above. The chute formed in accordance with this invention is fireproof and is uniform in appearance, strength and durability. This chute, it will be noted, can be erected at the same time that the silo or bin is being erected, thereby eliminatinlg the erection of special scaifolds and the From the foregoing it is believed that the construction, operation and advantages of the invention may be readily understood, and it is apparent that various changes may be made in the details disclosed without departing from the s irit of the invention, as expressed in the c aims.
